[jira] [Commented] (ZOOKEEPER-1027) chroot not transparent in zoo_create()

["Dheeraj Agrawal (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/ZOOKEEPER-1027?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13082401#comment-13082401 ] 

Dheeraj Agrawal commented on ZOOKEEPER-1027:
--------------------------------------------

Mahadev, this patch breaks windows build.
       //ZOOKEEPER-1027
        const char* client_path = sub_string(zh, res.path);

Windows doesn't like declaration of variables in middle of the code... The declaration of const char* client_path should be made just after the if condition at line 1898. 
   1898         if (sc->rc==0) {
   1899             const char* client_path;

> I've recently started to use the chroot functionality (introduced in
> 3.2.0) as part of my connect string.It mostly works as expected, but
> there is one case that is unexpected: when I create a path with
> zoo_create() I can retrieve the created path. This is very useful when
> you set the ZOO_SEQUENCE flag. Unfortunately the returned path
> includes the chroot as part of the path. This was unexpected to me: I
> expected that the chroot would be totally transparent. The
> documentation for zoo_create() says:
> "path_buffer : Buffer which will be filled with the path of the new
> node (this might be different than the supplied path because of the
> ZOO_SEQUENCE flag)."
> This gave me the impression that this flag is the only reason the
> returned path is different from the created path, but apparently it's
> not. Is this a bug or intended behavior? 
> I workaround this issue now by remembering the chroot in
> my wrapper code and after a call to zoo_create() i check if the returned
> path starts with the chroot. If it does, I remove it.
> My use case is to create a path with a sequence number and then delete
> this path later. Unfortunately I cannot delete the path because it has
> the chroot prepended to it, and thus it will result in two chroots.
> I believe this only affects the create functions.
